The invention belongs to the optical detection field, and discloses a rapid positioning device and positioning method for optical system test. The positioning device records the test posture of a standard optical system on a test device; after a tested optical system is changed, the posture reappears on the test device; the posture goes through a series of conversion through the positioning device; the normal direction of a benchmark mirror represents the test posture of the optical system, and the optical axis of an auto-collimation light pipe is used as the standard of a standard posture; in replacing the tested optical system again, the posture can reappear only by employing a two-dimensional platform to adjust the benchmark mirror normal to be parallel with the optical axis of an auto-collimation light pipe. The device has the characteristics of simple structure and high positioning accuracy, is suitable for assembly line work of mass products, and can directly perform test of relative specifications after positioning, thereby avoid a debugging process before test in the prior art.
Description
technical field [0001] The invention belongs to the field of optical detection, and relates to a rapid positioning device and a positioning method for optical system testing, which can be applied to rapid and batch detection and positioning of optical systems. Background technique [0002] In the field of optical inspection, especially for some optical systems that will be used in important production or living occasions, in order to judge whether they are qualified or not, some key indicators need to be tested one by one. However, this type of optical system is often mass-produced, so it has the characteristics of a large number of products to be inspected and similar inspection schemes. Before using some automatic detection equipment to detect it, it is necessary to adjust the optical axis of the optical system and the optical axis of the detection equipment to be parallel or coaxial, and different indicators have different requirements for the parallelism of the two axes ...
